Determination of Trace Uranium in Urine by Xenon-fluorometry

Liu Guowei,Chen Xiaoqiong,Sun Zhimin,Zhang Chuanwei(Sichuan Instutute of Materials and Technology,Sichuan Mianyang 621907)  
This paper uses the oxidation system of HNO3+HClO4+H2SO4,which can more thoroughly remove the organic compounds in urine,to treat urine sample.The sample treated by the improved means is applied to be measured by the trace uranium analyser of MUA Xenon-fluorometry.The precision is 5%,the recovery rate is 104%,and the detection limit is 0.036 μg/L.About 5 years of practice shows that the improved method meets the requirements of actual urine sample analysis.
